I am modeling a new SA-2 missile based on the proper shape for the missile when in post boost phase of flight... The real SA-2 is a two staged missile but is not modeled this way in FA... The missile retains its tail fins which is incorrect as the first stage is jettisoned as in the picture below...

So the new shape will be the upper stage and it will have a realistic shape as well as a highly detailed skin and have all correct fins and stenciling on the skin like in the picture shown below...
